WROUGHT-METAL SPLIT PU LLEY.

SPECIFICATION forming part of Letters Patent Lia/166,205, dated December29, 1891.

Application filed July 8, 1891. Serial No. 398,850. (No model.)

To aZZ whom it may concern: 7

Be it known that I, CHARLES D. WEEKS, of Akron, in the county of Summitand State of Ohio, have invented certain new and useful Improvements in\Vrought-Nletal Split Pulleys; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and usethe same.

My invention relates to improvements in wrought-metal split pulleys; andit consists in certain features of construction and in combination ofparts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an end elevation of a pulleyembodying my invention. Fig. 2 is an enlarged elevation, in transversesection, of one of the arms, taken on lines so as, Fig. 1.

The rim of the pulley is constructed in halves A A and of wrought-metalsheets or plates of suitable width for the face of the pulley. The oneend of each rim-section is bent at a sharp angle, as at a, to form oneof the primaryarms B. The two armsB B overlap each other and are curvedoutward, as at h b, to constitute the hub of the pulley, and the hub isconstructed to fit a given standard size of shaft. The overlappingsections of arms B B are drawn together by securing or clamping bolts bb on either side of the curved sections, whereby the hub of the pulleyis clamped so firmly to the shaft that no other fastening is required.The other end of each rim-section is bent inward at a more obtuse angle,as at a to form toes A for engaging an arm B, with securing-bolts b forsecuring these parts. By removing bolts 1) b the pulley can be dividedinto halves, and can therefore be readily mounted on or removed from theshaft.

0 C are arms or spokes for bracing, respectively, the central portionsof the rim-section. Arms 0 have toes O fastened to the rim, as shown,these arms having curved sections 0 and straight sections 0 for engagingthe exterior of the hub and for engaging the opposing section of an armB, to which latter section 0' is secured by means of the aforesaid bolts12. The different arms B and O, or either of them, may be curved incross-section-for instance, as shown in Fig. 2to stiffen the arms, andthis would be more likely done for a pulley of large diameter and broadface.

What I claim is- 1. A wrought pulley of the split variety the rimwhereof is constructed in two sections or halves, the one end of eachrim-section being bent inward to constitute an arm, the two armsoverlapping each other, the overlapping sections being curved outward toconstitute the hub, the other end of the rim-section havinginwardly-proj ecting toes'for engaging the opposing'arms, and withsecuring-bolts, substantially as shown, for fastening the arms togetherand thereby clamping the hub to the shaft and for fastening the opposingarms and toes, substantially as set forth.

2. In a wrought-metal split-pulley the rim whereof is constructed in twosections or halves, the one end of each rim-section being integral withthe pulley-arm, the two arms overlapping each other and constituting thehub of detachable arms having toes secured to the pulley-rim, thesedetachable arms having concaved sections engaging the periphery of thehub and having adjacent sections socured to the primary arms,substantially as set forth.

3. A split pulley comprising independent peripheral sections, eachsection having an integral arm curved outwardly to form a hub, said armssecured together on each side of the curved sections, substantially asset forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 7th day of May, 1891.

CHARLES D. WEEKS.
